Pour the beer and the sugar in a pot. Heat it up, till sugar is dissolved. Make sure it does not boil!
Put aside and let it cool off. Once cooled off, pour the Schnapps and add the vanilla.
If you use a vanilla bean, scrap the inside and add it. You can also toss the left over bean in the Schnapps, so you don´t waste anything.

Pour in bottles and you´re done!
Add some tags and you have a fancy gift.
